HETDDLE FRAME.

Application filed April 20, 1923.

T 0 all whom it may concern:

Be it known that T, JACOB KAUFMANN a citizen of the United States, residing at Flkins Park, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Heddle Frames, of which the following is a specification.

My invention relates to heddle frames for looms, and it relates more particularly to improved means for supporting the heddle bars intermediate their ends.

The principal object of my present invention is to provide improved means in a heddle frame for supporting the heddle bars intermediate their ends, which will securely support said bars against undesirable motion or displacement, but which, however, will permit the same to be readily and expeditiously mounted in and dismounted from the frame when desired.

My present invention contemplates the provision of an improved form of device of the character aforesaid, which is simple, durable and efficient for its intended purpose, and which is particularly adaptable for that type of heddle frames in which there are provided pairs of heddle supporting bars at the top and bottom, respectively, as is often the case when the warp ends controlled by the frame are closely arranged.

The nature and characteristic features of my invention will be more readily understood from the following description, taken in connection with the accompanying drawin s forming part hereof, in which:

igure 1 is a front elevation of a heddle frame with supporting devices embodying the main features of my present invention shown mounted therein;

Fig. 2 is a vertical transverse section thereof, enlarged, the section being taken approximately on the line 22 of Fig. 1;

Fig. 3 is a transverse sectional detail view, still further enlarged, the section being gaken approximately on the line 3-3 of Fig. 4 is a transverse sectional detail view, similar to Fig. 3, the section, however, being gaken approximately on the line 4-4 of 5 is a view similar to Fig. 3, but with the parts in the positions assumed when it is desired to insert the heddle bars in the sup- Serial No. 633,362.

porting device, or to remove the same therefrom; and

Fig. 6 is a view, partly in elevation and partly in section, taken approximately on the line 66 of Fig. 3.

Referring to the drawings, the heddle frame there shown comprises top and bottom' rails 8, usually made of wood and connected at their respective ends by means of the end straps 9 extending between said respective ends of the top and bottom rails 8. Arranged near the top and bottom rails in the usual manner are the heddle bars 10, upon which the heddles 11 are mounted and supported. The heddle bars 10 may be arranged in pairs at the top and bottom, as

shown, this arrangement being preferably provided for close installations of the warp ends to obviate crowding of the heddles on the heddle supporting bars.

In the particular embodiment of my invention shown in the drawings, the device for supporting the heddle bars intermediate their ends, which comprises the novel portion of my present invention, may include a pair of angle brackets 12, each having a horizontal extension 13 and a'vertical extension 14. The horizontal extensions 13 of the bracket members 12 are secured to the top and bottom rails 8 in any suitable manner. The vertical extensions 14 of the bracket members 12 are preferably secured to each other by means of shouldered rivets 15, so as to provide a space 16 between the vertical extensions 14: of the bracket members 12.

The vertical extensions 14 of the bracket members 12 are also each provided on each side with a recess 17, for the reception of the heddle supporting bars 10. The recesses 17 are of a width corresponding to the width of the heddle supporting bars 10, so that when said heddle supporting bars are mounted in said recesses, the same will be supported against vertical movement or displacement of the intermediate portions thereof with respect to the frame.

Mounted in the space 16 between the vertical extensions 14: of the bracket member 12 is a slide member 18 having a central slot 19 through which the rivets 15 pass, the slot l9 being of such length as to limit the move ment, in each direction, of the slide member.

18, for a purpose to be presently explained.

The slide member 18 is also provided on,

ice

each side with T-shaped recesses 20, the central portion of said recesses beingof awidth corresponding to the width of the recess 17 of the vertical extension 14 of the bracket member 12, and opening to the sides of the slide member as shown.

The bracket members 12 are also provided, adjacent the jointure between the horizontal extensions 13 and the vertical extensions 14, with a slot 22, and on the outer surface of one of the vertical extensions 14 there is secured a leaf spring 23, which may be secured in place by one of the rivets 15, and having its free end 24 extending into the slot 22 and bearing against the upper portion of the slide member 18. The free end of the leaf spring 23 may alternatively bear against the inner marginal edge ofthe slide member 18, or against the inner end of the slot 19 in said slide member, accordingly as the slide member is in one or the other of the locking positions, as will be hereinafter described.

When it is desired to mount the heddle supporting bars in the supporting device above described the slide member 18 is brought to an intermediate position as shown in Fig. 5 of the drawings, so that the central open portion of the "IT-shaped recess 20 thereof will register with the recess 17 in the vertical extensions of the bracket members 12, and the outer end of the slide member 18 will register with the outer ends of the vertical extensions 14 of the bracket members 12, as shown in Fig. 5 of the drawings. In this position the free end 24 of the leaf spring 23 will bear against the material of the slide member between the inner end of the slot 19 and the inner marginal edge of said slide member, and by reason of the frictional engagement thereof will temporarily hold said slide member in said intermedlate position as aforesaid. The

heddle supporting bars 10 may now be inserted in or removed from the supporting device, as required, and when the same are inserted and it is desired to use the frame in the loom, the slide member will be shifted either up or down, whereby the off-set portions of each T-shaped recess 20 will engage the heddle supporting bar, and the overhanging lip 21, resulting from the T-shape of the recess 20, will serve to confine the heddle supporting bar within the recess 17 of the vertical extension 14 of the bracket member 12. The leaf spring 24 will now engage either the inner marginal end of the slide member 18 or the inner end of the slot 19, accordingly as the slide member may be in the raised or lowered position,

To facilitate the manipulation of the slide member, the portions of the vertical extensions 14 of the bracket member 12 beyond the recesses 17 are preferably maden'arrower than the slide member 18, to thereby afi'ord e ias a better finger hold on the slide member when it is desired to move the same from one position to another.

It will be noted, however, that in the event The supporting device, constructed as aforesaid, will be found to be exceedingly useful and efficient for its intended purpose, in that the same will at all times function notwithstanding the continual stresses and knocks to which the heddle frames are subjected during the operation of the loom, and the likelihood of the heddle supporting bars becoming disconnected from the intermediate supporting device will be reduced to a minimum, as will be the destruction and disarrangement which usually results from fouling of parts of adjacent frames in the loom.

Having thus described the nature and characteristic features of my invention,
